Résumé en anglais

Testing a full size structure requires very expensive means. Therefore, the proposed methodology consists in testing a representative scaled down model, whose design is based on similitude laws. The purpose of this article is the constitution, for timber construction, of scale factors related to mechanical characteristics of frame connections, for 1/2 and 1/3 reduced scales. Firstly, scale factors were obtained by experimental tests on connections and then compared to the theoretical ones. Discrepancies have been noticed between experimental and theoretical scale factors. For most connection characteristics, discrepancies not only result from dispersions noticed on the three scales, but also from distortions in connections geometry. Secondly, a numerical approach will be developed to predict the timber construction behaviour, whose input data are provided by mechanical characteristics, described in this paper.< Réduire
